Atomic Radii
Atomic Radii refer to the size of an atom, indicating how big or small an atom is. Atomic Radii or size, is defined as the shortest distance between the center of an atom’s nucleus and its outermost shell. This concept is similar to the radius of a circle, with the nucleus being analogous to the circle’s center and the outermost orbital of the electron corresponding to the circle’s outer edge. In this article, we will discuss various concepts related to atomic radii of various elements in detail.
